To all whom it may concern." I

Be it known that I, LANoD'oN Moons, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Sheet-Metal Car-End Constructions, of which the following is a specification. I I I This invention relates to improvements in end structures for railway cars and more particularly to sheet metalends for freight cars. I II The end of a freight car is subject to very severe shocks and stresses on account ofthe tendency of the cargo to shift when the train starts and stops and in switching and also to the tendency of the superstructure of the car to weave while the train is in I motion. To strengthen this type of car, ends have been constructed of one or more sheets or panels of metal, usually steel,

which sheets or panels are formed with corrugations for rigidifying the structure to more readily meet impacts from without, cargo thrusts from within, and the racking strains from weaving.

It is the object of this invention to provide an end of the sheet metal type which is adaptable to either wooden car frames or all metal freightcars and that maybe employed for strengthening gondola cars, box cars, or other similar cars. It is a further object of this invention to provide the sheets or panels of the end with corrugations of particular contour that from their form and duration are peculiarly adapted to meet the stresses and strains already described. While the corrugations are preferably formed parallel, their relation to each other or their direction is immaterial, likewise the corrugations may be all pressed from one side of the sheet of metal or may be formed from opposite sides, as desired.

l/Vhile the preferred form of this invention is illustrated upon'the accompanying sheets of drawings, yet it is to be understood that minor detail changes may be made without departing from the scope thereof. I I I In the drawings: I I Figure 1 is a View in end elevation of a box car illustrating an embodiment of this invention. p

The box car end, as illustrated, comprises view I in PATENT .OFFICE.y-b

two or more sheets or panelsl, preferably of pressed steel, which are attached to the corner posts, end plate andendysill in'the usual manner. Figure 2 illustrates a means of attaching the panels to the wooden core ner posts 2 by flanging the endsof .thepanel and securing the flanges to the posts.

-A plurality of parallel 'strengtheningcorrugations 0r ribs are formed in each panel lwhich merge at their ends into the plane mar.- I

of the panel so that the panel has a fiat ginal portion about'itsedges. I v r a v The ribs or corrugatlonsare showninthe drawlng as pressedfrom thesame side of the metal sheet and decreaseconstantly in depth from center to ends, as, shownin' Fig-- ure 2. The contounof the corrugations at the ,center, is shown in Figure 3 from which it is seen that thealternate main walls 3 are substantially flat and parallel, form similar angles to the paneland are. preferably of less depth than the width of the portions 4 connecting them; The connecting portions are substantiallyflatand of equal width,in cross section, connecting the adjacent ends of the ma-inwalls and lie in planes substantially parallel to the panel- As the'depth decreases from center to ends, the main walls, maintaining substantially the same angular relation to the panel, decreasejconstantly and proportionately in width with ,theconnecting portions on both sides of said walls constantly and proportionately increasing in width with their longitudinal center lines parallel and. maintaining, in cross section,

their parallel relation to the plane; of the, panel until the oppositely disposed'connecting portions merge into their respective main Walls and into each other in the plane of; the panel, as shown in Figuresi, 5 and 6 and also in Figure 7 f 1 I I A Wooden lining 5 is preferably provided upon the interior loftheend and a number of filler blocks 6 are received Within and attached to a number of the ribs to Which the liningyis nailed, the blocks being beveled and tapered to fit -the ribs -'OI" corrugations and support I the lining parallel to I the end as shown. 1 I
